Fix "lorax -V" and add a "version is ???" to the log file so we can easily know
what version of lorax is used to build an iso.
Changed to try/import for versioning because the version file is autogenerated.
We should probably let the user know if something goes wrong with the
transaction or if a scriptlet fails. So: log the messages so we can find
(and, one hopes, fix) them later.
Some package scripts may call utilities using dbus. Since this is just a
chroot that will fail. This unsets DESKTOP and DBUS_SESSION_BUS_ADDRESS
to keep them from crashing.
This adds support for installing to a filesystem image instead of a
partitioned disk image. It requires Anaconda's --dirinstall support.
Also re-organized the code to break it up into smaller methods.
This speeds up iso creation in no-virt mode by removing the need to copy
the filesystem from the partitioned disk image to the filesystem image
that is used to make the squashfs image.
It used to give us (x/y) packagename, but now it only sends package
name. This was changed in yum commit 7e8c76173. For now default to
showing the zeros along with the package name so that it doesn't look
like an error.
kpartx can return before the devices are created. Use -s to wait.
Also remove -p p and let kpartx handle adding pX if needed, we use
whatever it outputs so there is no need to force a name.
This makes findkernels() look for any image named something like:
$PREFIX-$KERNELVER.img
and adds a corresponding entry to its returned data like:
kernel.$PREFIX.path = [path]
As a special backwards-compatibility case we use 'initrd' for the
attribute name if $PREFIX is 'initramfs'.
This gives us any extra initramfs images that may have been built using
the 'prefix' argument to rebuild_initrds().
If 'prefix' is passed to rebuild_initrds(), it will build a *new*
initramfs with a name like $PREFIX-$KERNELVER.img, rather than
overwriting the existing initramfs.
Dracut now makes the initrd with 600 permissions
for security reasons. These reasons do not apply
to install images, and we want the other tools
that use lorax to be able to read the initrd file.
When I switched execution over to execWith* functions I failed to
account for the use of CalledProcessError in various places. This
patch restores that behavior. All places that used check_call or
check_output now pass raise_err=True to the execWith* call.
--location specifies an iso directory tree to be used by virt-install
instead of the iso. This allows you to update the initrd in the tree for
debugging.
virt-install uses the images/pxeboot/ directory for initrd.img and
vmlinux.
An iso is still required for the LiveOS/squashfs.img stage2 file.
live media isn't exactly the same as the Anaconda install media. Right
now this amounts to needing a root= cmdline argument but in the future
there may be other differences.
This also reverts 5437557846 on the new copies of the templates.
Switch to using execWith* so that the command and its output can be
logged. To capture the output setup a logger named "program"
livemedia-creator captures all of this into program.log
- Add a check to livemedia-creator for /usr/bin/virt-install (#841566)
- Suggest the correct package for livemedia-creator's libvirt (#841552)
- Add to list of packages needed to build a livemedia-creator iso (#841594)
The 'systemctl' command can be used to enable, disable, or mask systemd
units inside the runtime being modified. Modify runtime-postinstall.tmpl
to use the 'systemctl' command.
We also no longer remove quota*.service or kexec*.service, since
these aren't enabled by default. And systemd-remount-api-vfs.service
should work correctly now, so we can leave it alone as well.
The '-cmd' functionality depends on the individual lorax template
commands raising errors, so they shouldn't do sys.exit().
Also, capture stderr along with stdout, and put both in the log.
There's something strange going on where unmounting a hfsplus volume
immediately after mounting it will fail with EBUSY.
This makes the umount fail, which makes the rmdir fail, which causes a
traceback, which breaks mkefiboot --apple.
It works fine if you wait a second and retry.. so do that.
Also, add the "lazy" argument so you can do lazy unmounts if you like.
Generally it's not a good idea for python libraries to set up loggers in
the body of the library.
Set up a NullHandler by default (as the logging module suggests), and
add a function to do the current logging setup during run().
From Harald Hoyer <harald@redhat.com>:
pollcdrom is used to poll for the install medium. A lot of CDROM drives
are not polled by the kernel correctly, so we have to actively poll for
the medium.
Some packages are critical to the compose. If --required
is specified in the template's installpkg command, lorax
will exit if the package is not available.
This adds support for creating an appliance description file for the
disk image. Mako templates are used to make it easy to support other
appliance targets. The included example works with virt-image.
Mac boot images are optional. Don't require hfsplus-tools
by default, but warn the user that he needs to install them
if he wants to create mac boot images.
When running with no-virt mode libvirt and virt-install are not needed
so make the import optional and update the usage info reflect that the
virt options are disabled.
There's a small amount of additional metadata required for the Mac boot
images to appear as bootable devices in the startup preferencs, so add
support for generating that.

Install the anaconda dracut module during 'install', use it when
rebuilding initramfs, and clean it up afterward.
Also install '.buildstamp' into the initramfs (the anconda module wants
it).
AMI images are un-partitioned filesystem images with a grub.conf that
is read by the pv-grub bootloader used by EC2. Most of the actual work
making the AMI is done in the kickstart. This just creates the image
file.
Fedora 17 changes top level directories like /bin, /lib, etc. to
symlinks to the corresponding dirs in /usr/
dracut can convert old systems to the new layout using its convertfs
module.
The installer no longer has access to the initrd's root. We need to
copy any needed files over to /sysroot before switching root. This
copies *.cfg and *.ks files.
It also adds the ability to add dracut hook scripts to the initramfs
from /usr/share/lorax/dracut_hooks/
This re-adds commit af6d4e2c50 which was
lost during the switch to the treebuilder branch.
In the latest method for booting the rootfs is in the LiveOS
directory of the media, not appended to the initrd. Detect this
and mount the iso and pass the CDLABEL to virt-install.
Some repos may contain anaconda packages for more architectures,
so it's not possible to get the right buildarch.
This patch allows optional specifying of the buildarch on the
command line when running lorax.
If the buildarch is not specified manually, lorax tries to get
it from the anaconda package as before.
If there's no anaconda package in the repository, don't fallback
to the system architecture and continue, because this is pointless.
We need the anaconda package.
When considering a package's filelist (e.g. for things like removefrom
--allbut), we might need to also include the %ghost files, so make
_filelist() add them to its returned list.
This runs anaconda directly, using the --image install feature. The host
system should be the same release as the target system in order to avoid
unexpected problems.
livemedia-creator uses an anaconda install media iso to install to a
file image. virt-install is used to execute the kickstart. lorax is used
to post-process the image file and create a bootable .iso from it.
Future additions will allow creation of EC2 images and output xml
details about the install.
The anaconda execWithRedirect and execWithCapture functions are too
useful not to include. They also allow you to log all the execuatable's
output to a logfile. Added them under executils.py module which uses
the pylorax and a new program logger.
Allow passing of size to create_runtime, add PartitionMount context
to use kpartx to mount partitioned file images. Add resetting the
selinux context on the newly created rootfs.
This means that any (non-ignored) command error will cause lorax to
exit.
Do note, however, that some commands (e.g. remove, installpkg) don't
raise exceptions and therefore will not cause lorax to exit.
Makefile-style "-cmd" syntax lets us run a command and ignore any
resulting errors. This is a more general version of what copyif/moveif
were trying to accomplish, so we can drop those commands.
New images find their root device by looking at the CDLABEL. Since pungi
is building ISO images separately from lorax, if it uses a different ISO
Volume Label we'll end up with unbootable images.
This changes the volume labels to match what pungi uses, so both should
boot OK.
- Log the error message (and the line causing the error) to console
- Log the whole exception (with some excess junk removed) to debuglog
- don't immediately SystemExit if the template won't parse
- clean up some comments
This lets us easily do whitelisting instead of blacklisting during
runtime cleanup. For example:
removefrom xfsprogs --allbut /sbin/* /usr/sbin/xfs_admin
would remove everything from the xfsprogs package except files in /sbin
and /usr/sbin/xfs_admin.
A few things in runtime-cleanup have been converted to use --allbut. The
only difference in the created runtime image is that we're deleting
/usr/share/kde4 from fedora-logos.
make sure that runner.templatedir gets set to a useful default if
initialized with None, and and make sure we pass templatedir to
LoraxTemplateRunner.__init__ (so it'll get initialized properly)
emit a useful log message if we attempt to removepkg something that
isn't installed, or if a glob used in a removefrom line matches no
files.
this will help us keep the templates cleaner.
* add bcj arch dict to ArchData
* add "compression" settings back to __init__.py
* pass them to treebuilder.create_runtime
* pass them through to imgutils.mksquashfs
To build F15 images we need to remove systemd and set up loader as init
(see runtime-cleanup and runtime-postinstall).
We also need to add a hack to dracut so loader won't freak out when it
gets started by anaconda - see the file we're adding to the initramfs in
treebuilder.py.
(There's also an extra bonus hack for working around a bug in dracut if
/proc/cmdline is empty - SEE IF YOU CAN SPOT IT!!!)
Let's let yum handle the magic of figuring out what basearch is. And
since basearch will match userspace, libdir should match basearch.
This fixes stuff on pre-F16 ppc64 (where basearch is ppc and thus has a
different libdir).
module-info and the updated depmod stuff need to be inside the runtime
image, so this needs to happen before create_runtime. Accordingly,
generate_module_data gets moved to RuntimeBuilder.
dracut's dmsquash-live-root won't recognize the image as a squashfs live
image unless its name matches "*squashfs.img", so choose the filename
accordingly. Then pass the name to the TreeBuilder so it can move it
into place.
add lib/dracut/hooks/pre-pivot/99anaconda-umount.sh to unmount things
before starting anaconda (because loader explodes if /{dev,sys,proc}
are mounted when it starts)
Add setup_init() and setup_s390_init() to installtree.py to handle
init setup, and stop using systemd so we can make F15 images.
This reverts commit b58190d660.
"from glob import glob" instead of "import glob"
rename args to BaseBuilder.runtemplate
set up 'exists' and 'glob' in runtemplate rather than getdefaults
Since we want all the modules in the runtime image, there's no need
to deal with the individual kernels. And workdir was only being used
to mess with the modules, so we don't need that either.
This allows us to create these objects without needing workdir,
which means we can use them outside of __init__.py.
We can also write them directly to their final destination
instead of writing them to the workdir and then copying them in.
Any decisions about arch-specific stuff should happen in the Lorax class
or the arch-specific templates/code. Move that logic up to Lorax.run()
and remove installtree.basearch.
getdata(cmd) will return a generator that yields every token on every
line that starts with the token "cmd". getdata(cmd, mode="lines") will
yield a list for each line rather than every individual token.
this simplifies some things in __init__.py.
arch has three attributes: .buildarch, .basearch, and .libdir
product has six: .name, .version, .release, .variant, .bugurl, and
is_beta
This makes it easier to pass this data into functions/templates.
TreeBuilder uses templates full of commands (like ramdisk.ltmpl) to
create the output tree and boot images. There are 4 arch-specific
templates, plus a bonus EFI template which can handle EFI image creation
for any arch that implements EFI.
This adds the new "mkefiboot" cmd, which creates an efiboot img in the
magical way that EFI requires. There doesn't seem to be a good tool for
this (unlike the existing tools for all the other weirdo boot image
types) so it was necessary to create one.
This contains simple functions for creating disk images:
mkcpio, mksquashfs, mkdosimg, mkext4img, mkbtrfsimg
And the helper functions they use:
truncate, loop_{attach,detach}, dm_{attach,detach},
mount/umount, estimate_size, roundup, cpio_copytree
This adds the remove() function, which works a lot like rm -rf - if you
remove() a file, it uses os.unlink, and if you remove() a directory it
uses shutils.rmtree().
We're already using find and cpio subprocesses, so using
one more subprocess is not a problem. With this approach
we can pipe cpio to the xz/gzip command, which should
help with the memory issues.
